摘要
本文利用紫外－可见吸收光谱法、顺磁共振（ＥＳＲ）法系统地研究了多甲川键菁染料光氧化反应机理，结果表明，单线态氧（￣１Ｏ＿２）、超氧阴离子是导致染料光褪色的主要因素，而在没有氧气存在下，Ｄｙｅ￣－也促使染料光褪色。
In this paper, the photcoxidation mechanisms of polymethylene chain cyanine dyes were studied by U-V spectroscopy and Electron Spin Resonance (ESR). It was revealed that singlet oxygen (￣1O_2)、 superoxide were the main factors causing the photofading of dyes ,and dye would cause the photofading of dyes without oxygen.
